AMD Radeon HD 7660D On Linux
In my Linux preview article to the AMD A10-5800K "Trinity" APU I shared some initial benchmarks of the integrated Radeon HD 7660D graphics and compared those results to various NVIDIA and AMD discrete graphics cards. In this article are more Radeon HD 7660D Linux graphics benchmarks. In particular, there are results from the A10-5800K graphics when overclocking the GPU core along with benchmarks comparing this high-end Trinity APU to last year's A8-3870K "Llano" APU with Radeon HD 6550D graphics.
Benchmarking in this article was done with the Linux Catalyst driver -- the fglrx 9.0.2 / OpenGL 4.2.11903 driver release currently found in the Ubuntu 12.10 repository. Attempting to benchmark the new Trinity APU graphics was attempted on the open-source Radeon Gallium3D stack too using the very latest components, but it was an unstable and troubling experience. When there's time for things to settle a bit more, the Radeon HD 7660D will be re-attempted to run with the open-source OpenGL stack.
Most of the A10-5800K / Radeon HD 7660D Linux benchmarks are now complete, including comparisons to other processors, so there will be several AMD Trinity Linux articles coming out in the next few days.
First up in this article is the A10-5800K with Radeon HD 7660D graphics compared to the AMD A8-3870K Llano with Radeon HD 6550D graphics when both were using the same software stack. Both Radeon GPUs were running at their stock speeds. For comparing the Radeon HD 7660D graphics to other NVIDIA/AMD graphics cards, see last week's article for those numbers. Following the Llano vs. Trinity results are the Trinity GPU overclocking numbers.
